Title: Monitoring device for battery charging unit - has comparator based on threshold and breakdown voltages of semiconductors
Inventor: RABE DIETER ING GRAD
IPC: H02J7/00
Filed: 1975-02-19
Abstract: The monitoring device for a battery charging unit has a comparator which is based on the threshold and breakdown voltages of semiconductors. The unit is designed for three-stage charging, and the comparator compares nominal with actual values of the charging process. The comparator comprises a controlled rectifier whose voltage is applied through a resistor to the comparator and a voltage derived from the charging current is also applied to the comparator. A current measuring resistor is inserted into the comparator circuit, to which a current is directed exclusively at the beginning of a new charging stage. The two-pole input of a signal converter detects this current connection and is connected to the current measuring resistor (9).

Title: Wiring arrangement for telephone equipment - uses prewired guide plates instead of plug connectors giving fewer contacts
Inventor: ZELL KARL
IPC: H01R43/033
Filed: 1975-03-27
Abstract: The wiring arrangement is for telephone equipment where permanently installed but separated circuits have to be interconnected. The wires (1) are threaded into the correct holes in a guide plate (3', 3") which exactly matches the connector pin pattern on the circuit units requiring interconnection. The guide plate is then brought down over the pins and the wire ends wrapped on or otherwise connected. By making the holes in the guide plate large enough the latter may then be removed and reused. It is an aid to installation if the wire ends are bared and located in the guide plate, for example in a small slot in the hole.

Title: Multi-layer strip production process - produces stainless steel clad sheet at relatively low cost
Inventor: SENDZIMIR TADEUSZ
IPC: B23K20/14
Filed: 1975-04-11
Abstract: Multi-layer strip prodn. process comprises hot rolling a pack of metal slabs in a heavy, one-step elongation in a cyclic mill to strip gauge. First a pack of slabs is assembled and fed to the feed rools of a cyclic mill at a temp. below the oxidn. temp. High intensity heat is applied to the two outside faces of the pack at an area up-stream of the cyclic mill. The area at which heat is applied is at a distance from the first contact point of the work rolls of the cyclic mill such that the interfaces between the slabs making up the pack and which are to be bonded, do not reach oxidn. temp. before the first contact point, from which point on there is no danger of oxidn. The heated pack pref. passes between insulating means from the point of application of heat to the work of the cyclic mill.

Title: Printer for machine-readable and human-readable characters - characters are placed one above the other and both have the same width
Inventor: HATSELL WILLIAM ALDEN
IPC: G06K1/12
Filed: 1975-08-11
Abstract: The characters are formed as electro-static charges on a web (100) moved past stationary electrodes. The machine-readable characters are formed by a bar-shaped electrode (112) whose length is perpendicular to the direction of movement of the web so that the characters can be formed by a code employing lines of different width by selective energisation of the electrode as the web moves. The human-readable characters are formed by point electrodes (114) which generate the characters from dots and lines, the lines being created by the movement of the web. May be used for labels.

Title: Cutter bit for machining bevel gears - has acute angle profile bit to facilitate regrinding and provide clamping surface
Inventor: REISE EBERHARDT
IPC: B23F21/22
Filed: 1975-10-29
Abstract: The inserted knife or cutter bit is used in cutting heads for mfg. gear wheels, esp. bevel gears. The shank of the bit is provided with a flank-free surface with a crown-free surface and a clamping surface forming the cutting edges. At least two of the four surfaces forming the cross-section of the bit make an angle below 90 deg., and one of the two surfaces forms the clamping surface.

Title: Coding and decoding characteristics monitor - measures deviations using D-A converter, memory and digital comparators
Inventor: GASTEIGER RICHARD
IPC: H03M1/00
Filed: 1976-05-31
Abstract: The monitor is for measuring an iterative coder/decoder deviations from wanted coding/decoding characteristics. It passes the digital signals used to check the coding and decoding characteristics of the CODEC simultaneously to the CODEC input and to a calibrated D/A converter input and to the input of a memory. An analog comparator compares the CODEC analog output with the converter's output and produces an error signal if the difference exceeds a given amount. After passing to the comparator, the converter's output is passed to the CODEC's input where it is converted into a digital signal and compared with the digital signal retained by the memory.

Inventor: MATISCHEW WLADIMIR ALEKSANDROW
IPC: C07C7/152
Filed: 1976-08-19
Abstract: Individual n-paraffins are recovered from petroleum feed mixts. by (i) contacting the feed with crystalline urea in the presence of an activator (I) at a temp. being the upper limit for complex formation of the specific n-paraffin to be isolated (the highest mol. wt. n-paraffin present) (ii) separating the complex, (iii) washing the complex with the n-paraffin to be isolated, (iv) heating the complex to a temp. 2-5 degrees C higher than its decomposition print and (v) recovering the individual n-paraffin. The residual petroleum feed is recycled and the process is repeated to recover any further individual n-paraffins in order or decreasing mol. wt. The process provides a simple technique of isolating highly pure (>=99 wt.%) n-paraffins, suitable e.g. as starting materials in the prodn. of higher fatty alcohols, proteins with biodegradable detergents.

Title: Lifting girder for cooling bed - for cooling and cross transport of sheet metal using supports which are periodically pushed to and fro
Inventor: KRUEGER BERND
IPC: B21B43/02
Filed: 1976-10-12
Abstract: The arrangement is used to lift sheets of large width (over 4m) from a transport roller to a cooling bed or vice versa. The end section (3) of the arrangement can be moved close to the transport roller (9) and is provided with a support grid. The lifting stroke of the end section can be increased by the stroke of the support grid (20) up to the amount of the max. sheet width. This prevents that the transport roller is blocked, when large sheets have to be transferred in several steps. The support grids are mounted on carriers (5), which have sloping tracks (6) and are moved by a drive over rollers (8).
